Many people’s version-control method of choice is to copy files into another directory (perhaps a time-stamped directory, if they’re clever). Below you can see how this works; we created a branch “alpha” then deleted it using this command. We will use git, developed by Linus Torvalds, the “Linu” in Linux. Anyone who downloads your notebook has to run the code to see plots/results. To deal with this problem, Centralized Version Control Systems (CVCSs) were developed. Git is a distributed version-control system for tracking changes in any set of files, originally designed for coordinating work among programmers cooperating on source code during software development. This is where Distributed Version Control Systems (DVCSs) step in. However, GitHub is mainly a hosting platform for hosting Git repositories online. It was initially designed and developed by Linux Torvalds to use for the Linux kernel source code, so you know it has an amazing pedigree. This allows the team to continuously improve its product. Instead of manually scanning branches of code and associated notes, version control allows for a central repository that is organized, logical, and facilitates file updates, notation, and even merging. This approach is very common because it is so simple, but it is also incredibly error prone. Any changes made in alpha will NOT affect master unless additional steps are taken.
